Restore Control Over Your Truck’s Electronics
Is your Silverado or Sierra acting possessed? Flickering lights, a horn that won’t quit, power windows with a mind of their own, or a frustrating no-start condition are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of bizarre and unpredictable problems. I’ve spent two decades in the garage, and I’ve seen how a single failing module can make a perfectly good truck feel unreliable and unsafe.
This isn’t just a replacement part; it’s a straightforward, permanent fix. We offer a pre-programmed Body Control Module, part number 13594692, that eliminates the need for expensive dealership visits and complex programming tools. Our unique cloning service makes the repair process as simple as possible. You send us your original BCM, and we transfer all the critical, vehicle-specific data—like VIN, mileage, and key information—to this replacement unit. The module you receive back will be a true plug-and-play solution, ready to install right out of the box.
From the Diagnostic Bay: The Case of the Phantom Horn
A customer brought in his 2014 Sierra 1500, completely fed up. His horn would start blaring randomly, sometimes in the middle of the night, forcing him to disconnect the battery. His power locks were also intermittent. He’d already replaced the horn relay and checked the steering wheel clock spring. After connecting my scan tool, I saw several U-codes (communication errors) pointing to the BCM. Instead of a new, unprogrammed module from the dealer which would have cost him over $800 after programming, we used a cloned unit. The entire swap took less than 30 minutes, and the phantom horn was silenced for good. This is a perfect example of how a cloned 2014 Silverado 1500 BCM can save hundreds of dollars and hours of frustration.
Is Your Truck Showing These BCM Failure Symptoms?
A failing BCM often creates electrical chaos. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Security system warning lights on the dash or alarm randomly activating.
- ✔ Inconsistent windshield wiper operation.
- ✔ A no-start or no-crank condition, even with a good battery and starter.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable job for a DIYer with basic tools. For the 2014 Silverado/Sierra, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting any electrical work.
- Locate the BCM: On most trucks, you’ll need to remove the lower dash panel beneath the steering wheel to access the module.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reassemble the dash panel, reconnect the negative battery terminal, and start the vehicle. Test all body functions—lights, locks, windows, horn, etc.—to confirm the repair.
Post-Installation Checks
Because this module is cloned from your original, most vehicles will not require any additional procedures. However, in some cases, you may need to perform a simple relearn. Please note:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a professional scan tool to sync the systems. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be required to ensure proper brake light and traction control functionality.
Disclaimer: Always consult a factory service manual for procedures specific to your vehicle’s exact year and model.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will transfer its unique programming to the replacement unit. We then ship the ready-to-install module back to you, typically within 1-2 business days.
Do I need to send my keys?
No. Because we are cloning all the data from your original module, including the key information, you do not need to send us your keys. The replacement BCM will recognize your existing keys upon installation.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, the core programming data on the memory chip is still readable. We have a high success rate in extracting data from non-communicating modules. Contact us if you have concerns about your specific situation.
Is there a core charge for this part?
No, there is no core charge. Our service is based on cloning your original module, so you will not need to return it after receiving the programmed replacement.
Will this fix my specific problem?
This part is a solution for failures within the Body Control Module itself. While the symptoms listed are very common for a bad BCM, proper vehicle diagnosis is always recommended to rule out other issues like wiring faults or bad sensors.
